1. Bedding the tape
After the joint filler has been applied, a paper tape is bedded
in. Our trainees learnt the importance of doing this properly. If is done incorrectly you may get cracking, or the tape can
bubble and cause problems with later coats and the overall finish.
2.Joint cement
Next a layer of joint cement goes in to blend the joints into the wall
and cover the tape. Care was taken not to overfill the joint, as this would result in a bump which will need to be rubbed
down once dry. At this stage the trainees filled in the screw heads too.
3.Topcoat
The topcoat is a finer coat. Using a trowel or filler knife, the trainees
spread joint cement over the joint, 'feathering' it out beyond the previous coat. The better the application of the filler,
the easier it is to rub down.
